What is the high-speed signals that pass along the axons of nerve cells called?
The high-speed signals that pass along the axon are called action potentials. They spread in a wave of depolarization.
What signal travels along the axon?
The high-speed signals that pass along the axon are called action potentials. They spread in a wave of depolarization.
Microscopic fiber that carries the nervous impulse along a nerve cell?
axon
What influences the speed of a nerve impulse?
the diameter of an axon
Mechanism of nerve conduction?
Nerve impulses are conducted along the axon in the myelinated nerve fiber with causes the polarity of the nerve.
What is function of axon terminal?
the primary function is to send nerve signals to the various parts of the body
What is the function axon terminal?
the primary function is to send nerve signals to the various parts of the body
What are the high speed signals that pass along axons of the nerve cells?
A nerve impulse is an electrical signal that travels along an axon. There is an electrical difference between the inside of the axon and its surroundings, like a tiny battery. When the nerve is activated, there is a sudden change in the voltage across the wall of the axon, caused by the movement of ions in and out of the neuron.This triggers a wave of electrical activity that passes from the cell body along the length of the axon to the synapse.The speed of nerve impulses varies enormously in different types of neuron. The fastest travel at about 250 mph, faster than a Formula 1 racing car. For the impulse to travel quickly, the axon needs to be thick and well insulated.This uses a lot of space and energy, however, and is found only in neurons that need to transfer information urgently.For example, if you burn your fingers it is important that your brain gets the message to withdraw your hand very quickly.
COnduction speed of a nerve fiber would be the fastest in a?
...in a myelinated axon.
What is the material surrounding the axon that increases the speed of the nerve impulse?
myellin
What part of nerve cell is adjacent to neuromuscular junction?
The axon terminal of a nerve cell is adjacent to the neuromuscular junction. The axon terminal releases neurotransmitters that transmit signals across the synapse to the muscle fiber. This signal triggers muscle contraction.
Do nerves contain axons?
Nerves are like trees. The have branches call axons.
